Prototyping for requirements elicitation and validation: A participative prototype evaluation methodology

Prototyping is widely recommended as an excellent mechanism for requirements elicitation and validation. However, few details are available on how prototypes should be used for this purpose, especially in a group environment. The goal of this research is to develop and evaluate a methodology for using prototyping to elicit and validate requirements from large user groups. An initial prototype evaluation methodology was developed, assessed during a pilot case study, and revised to support different evaluation phases and types. The revised participative prototype evaluation methodology provides a specific structure for each prototype evaluation phase with derailed methods and GroupSystems tools defined for each evaluation type. An overview of the face-to-face procedures by evaluation type is included in this paper.
